CHS Blood Pressure Measurement Techniques & Monitoring 2

Question 1

What is the standard duration for ambulatory blood pressure monitoring (ABPM)?

Accepted Answer

24 hours

Answer

Standard ABPM is performed over 24 hours to capture blood pressure variations across both daytime activity and nighttime sleep.

Question 2

What is the normal 'dipping' pattern identified on ambulatory blood pressure monitoring?

Accepted Answer

10–20% reduction in nighttime BP compared to daytime

Answer

Normal dippers show a 10–20% reduction in nighttime blood pressure; non-dipping is associated with increased cardiovascular and renal risk.

Question 3

According to ABPM criteria, what 24-hour average blood pressure threshold defines hypertension?

Accepted Answer

≥135/85 mmHg

Answer

The 24-hour ABPM hypertension threshold is ≥135/85 mmHg, which is lower than the office measurement threshold of 140/90 mmHg.

Question 4

Which condition is defined as consistently elevated office blood pressure with normal readings confirmed by ABPM or home monitoring?

Accepted Answer

White coat hypertension

Answer

White coat hypertension is characterized by office BP ≥140/90 mmHg with normal out-of-office BP (<130/80 mmHg on ABPM), likely due to an alerting response in the clinical setting.

Question 5

What is 'masked hypertension'?

Accepted Answer

Normal office BP with elevated readings on ABPM or home monitoring

Answer

Masked hypertension is characterized by normal office BP with elevated out-of-office measurements and carries similar cardiovascular risk to sustained hypertension.
